System for adjusting radiation target sites dynamically according to moving states of target object and for creating lookup table of the moving states

Abstract

A system for adjusting radiation target sites dynamically according to the moving states of a target object and for creating a lookup table of the moving states includes a detection chip, a radiation generation device, and a lookup table. The detection chip can be fixed on the target object to detect the current moving state of the target object. The detection chip or the radiation generation device, both configured for wireless signal transmission to each other, can activate or deactivate the radiation emitters of the radiation generation device individually according to the current moving state of the target object and the contents of the lookup table. As the system uses wireless transmission, and the lookup table has recorded the working state of each radiation emitter in each moving state of the target object, radiotherapy can be performed without a large number of tubes or sensors.
